Öz

Bu çalışmada, Kuzey Ege Denizi’nde (Saroz Körfezi) Fangri balığının toplam boy (TL) ile toplam ağırlık (TW) arasındaki ilişki, yaş, büyüme ve otolit boyu (OL) - otolit ağırlığı (OW), balık boyu (TL) - otolit boyu (OL), balık ağırlığı (TW) - otolit boyu (OL), otolit boyu (OL) - otolit genişliği (OWi) arasındaki morfometrik ilişkiler incelenmiştir. Toplam 100 adet balık üzerinde yapılan ölçümlerde minimum boy 9,6 cm, maksimum boy 44,4 cm; minimum ağırlık 17,1 g, maksimum ağırlık 1372,5 g olarak tespit edilmiştir. Otolit ağırlığı minimum 0,0181 g, maksimum 0,1456 g; otolit boyu minimum 0,52 cm, maksimum 1,17 cm olarak ölçülmüştür. Boy-ağırlık ilişkisi TW=0,021*TL2,885 (r2=0,98), otolit boyu - otolit ağırlığı OW=0,105*OL2,609 (r2=0,92), toplam boy - otolit boyu OL=0,024*TL+0,249 (r2=0,83) otolit boyu - toplam ağırlık OL=0,235*TW0,237 (r2=0,81) otolit boyu - otolit genişliği OWi=0.501*OL+0.116 (r2=0.832) ilişkileri tespit edilmiştir. En büyük yaş 9 olarak belirlenmiş, von Bertalanffy büyüme parametreleri L∞=51,59 cm, K=0,12 yıl-1ve t0= -1,13 yıl olarak hesaplanmıştır

Abstract

In this study, total length (TL) – total weight (TW) relationship, age, growth, and the morphometric relationships of otolith between otolith length (OL) and otolith weight (OW), total length (TL) and otolith length (OL), total weight (TW) and otolith length (OL), otolith width (OWi) and otolith length (OL) of Pagrus pagrus were investigated in Saros Bay (North Aegean Sea). A total of 100 specimens were measured as minimum TL 9.6 cm, maximum TL 44.4 cm, and minimum TW 17.1 g and maximum TW 1372.5 g. A total of 55 otoliths were measured as minimum OL 0.52 cm, maximum OL 1.17 cm, minimum OW 0.0181 g, and maximum OW 0.1456 g. The relationships between TL and TW, OL and OW, TL and OL, OL and TW, OL and OWi were determined as TW=0.021*TL2.885 (r2=0.98), OW=0.105*OL2.609 (r2=0.929), OL=0.024*TL+0.249 (r2=0.839), TW=0.235*OL0.237 (r2=0.814), and OWi=0.501*OL+0.116 (r2=0.832), respectively. Maximum age was 9 years for P. pagrus and von Bertalanffy growth parameters were estimated as L∞=51.59 cm, K=0.12 year-1 and t0=-1.13 year.
